According to the American Thyroid Association, you should begin screening for thyroid dysfunction at age 35, and take follow-up tests every 5 years.⁷

You should take our Standard Thyroid Test if you have questions about your thyroid health or are experiencing early warning signs or symptoms of thyroid problems.

Low TSH and high T4 levels typically indicate an overactive thyroid (hyperthyroidism), suggesting that the thyroid gland is producing too much thyroid hormone. Common symptoms may include rapid heartbeat, weight loss, anxiety, and heat sensitivity.
 

It’s important to consult with your healthcare provider for proper interpretation and potential follow-up testing or treatment.

High TSH levels often typically indicate an underactive thyroid (hypothyroidism). When the thyroid gland doesn't produce enough thyroid hormone, the pituitary gland responds by increasing TSH production to stimulate the thyroid. Common symptoms may include fatigue, weight gain, cold sensitivity, and depression. It’s important to consult with your healthcare provider for proper interpretation and potential follow-up testing or treatment.

Normal TSH levels vary by age.

Consult with your healthcare provider if you have questions or concerns about your results.

Your testing will be performed in a CLIA-certified clinical laboratory.

Your results will be provided to you through our secure online portal to view or print.
